T-Series Darkroom Model

Description

Page Content

​

Overview

A range designed for photographic, medical, dental and veterinarian applications - used also for opticians and other specialist applications. Most darkrooms need a minimum of ten air changes per hour for comfort and efficiency. For rooms containing heat producing equipment (eg: print glazers) a higher rate of air change may be desirable.

The Darkroom model has two cowls, the interior cowl being designed to give light protection. It can be installed in windows, partitions, external walls or roofs. Extended fixing rods for fixing thicknesses up to 370mm are supplied with the unit. Provision should be made for adequate air replacement through Vent-Axia non-vision grilles. For areas requiring total light exclusion, contact your local Vent-Axia Sales Office.

Product Specification

Shutter

With energy savings in mind TX models are supplied complete with an integral instantaneous automatic louvre shutter concealed behind the interior cowl. Operates on intake and extract at any angle of mounting.

The shutter is electronically controlled by an actuator with a damped action giving quiet operation during instant opening and closing. The interlocking edges of the shutter blades provide maximum backdraught protection.

When used with a T-Series controller, the shutter can be set open with the fan motor switched Off to provide natural ventilation without the security risk of an open window.

TL models do not have a shutter. They are suitable for room to room systems and where there is a need for ventilation of specialised equipment. The TL model will also provide natural ventilation where required when the unit is switched Off. Suitable for operation in ambient temperatures from -40°C to +50°C.

Typical Specifications

The fan should be able to give a minimum of 10 air changes per hour, it should have two cowls to give light protection while mounted in windows partitions, external walls and roofs. The fan should be able to extract through walls up to 370mm thick by use of extended fixing rods.

The fan should have a speed control pack which enables high, medium and low speed to be set to suit room size or required duty.

The fan should be fully reversible and be able to be controlled by using variable speed controllers or by humidity, air quality or PIR sensors.

The fan should incorporate an electronically controlled instantaneous shutter mechanism that has a facility to be in an open state without the fan running for passive ventilation.

The unit should meet with Document F of the Building Regulations and be BEAB approved.

The motor should be suitable to run at any angle and suitable for operation in ambient temperatures from -40°C to +50°C and should be fitted with self resetting Standard Thermal Overload Protection (S.T.O.P.).
